Cool!..............LITERALLY!................

A board coated in the new polymer paint stays significantly cooler than its surroundings, even in direct sunlight, as seen under ultraviolet infrared lights. (Image courtesy of Columbia University.) There, fixed it. Dumb reporters.

Thank you. Sometimes, I want to strangle reporters.

the researchers were able to create a “white paint” that doesn’t absorb UV radiation.

I wonder if durability is effected?

but there was no consensus on how to get transparent polymers to reflect sunlight
Beer is transmissive.
Beer Foam is reflective.

What’s really impressive, here, is that they have achieved high reflectivity in the visible wavelengths AND high emissivity in the thermal wavelengths. Clever to achieve it with foam.

Beer is good. There’s also a lot of physics to learn from a glass of beer.

"Now is a critical time to develop promising solutions for sustainable humanity,"
Anyone else find themselves interested in a product or service, and then see this sustainability crap and find it not so interesting anymore?
I'm getting to the point where I don't care how much I want/need something, I'm not going to support this silliness anymore.

I need some of that for painting my beach house in the South Pacific... after I can afford to buy a beach house in the South Pacific.

the researchers were able to create a “white paint” that doesn’t absorb UV radiation. Here's the original YouTube video where that image with the ultraviolet caption originated from. In the video the image is clearly from an infrared camera, with a temperature scale on the right side showing the correlation between the false colors and temperature. You can watch the entire video, but I have cued it up to the relevant shot here:
https://youtu.be/8lTdZ-U0Qm8?t=107
The underlying abstract paper does mention UV reflectance as an advantage of the coating not breaking down after prolonged exposure to sunlight.
But the captioned image is NOT of ultraviolet light. It is of near infrared.

It’s racist paint.
